摘要/Abstract

摘要： 在添加高效降解菌剂的基础上，研究了营养物质的种类、添加量以及不同表面活性剂对石油污染土壤修复效果的影响。结果表明，营养物质种类对修复过程的影响显著，添加N、P含量较高的硝基磷酸铵以及自行配制的NH4NO3：NH4H2PO4=5：1混合肥料的处理石油降解率比对照分别提高15.1%以及17.2%，当土壤中C：N的比例控制在100：7.05~100：9.4之间时，修复效果较好，且肥料的添加宜采用少量多次的原则；添加表面活性剂的处理中，鼠李糖脂的处理效果最好，石油降解率比对照提高8%，优于其他化学表面活性剂处理。

Abstract: We addressed the impact of nutrient type and addition amount, and different surfactanton bioremediation effect of petroleum contaminated soil based on the addition of efficientoildegradation agent.Results show that nutrient type significantly affects the remediation process. Degradation rates of oil processed through addition of nitro ammonium phosphate and the mixed nitrogenrichfertilizer (NH4NO3：NH4H2PO4=5：1) are respectively 15.1% and 17.2% higher than that of the control.Bioremediation effect is better when the ratio of carbon and nitrogen is between 100：7.05 and 100：9.4, and the addition of fertilizer should be multiplelowdose. The processing effect of rhamnolipid is better than that of other chemical surfactants and its oildegradation rate is 8% higher than that of the control, superior to other chemical surfactants.

Key words: petroleum contaminated soil, bioremediation, surfactant, additive, nutrient
